FEEDING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 230,544, dated July 27,1880,

Application filed February 26, 1880.

T 0 all whom it may concern Be it known that I, DEXTER W. GooDELL, ofFlorence, in the county of Hampshire and State of Massachusetts, haveinvented certain new and useful Improvements in Feeding Mechanisms forSewing-Machines, of which the following is a specification.

The invention consists in certain novel combinations of devices with themain shaft which actuates the needle-bar, shuttle, and feeder, wherebymotion is transmitted from said main shaft to an oscillating andlongitudinally-adjustable feed-shaft in a smooth, positive, and easymanner.

It also consists in a connecting-rod of novel construction fortransmitting motion from the main shaft to said oscillating andlongitudinally-adjustable feed-shaft, in combination with mechanism foractuating the connectingrod from said main shaft.

The accompanying drawings only illustrate so much of a sewing-machine asis necessary to explain myinvention, the remaining portions of themachine not necessarily differing from other shuttle-machines in whichthe feedshaft, arranged below the bed, is operated by connections with aneedle-operating shaft in the arm or goose-neck of the machine.

Figure 1 represents a transverse vertical section through a portion of asewing-machine embodying my invention. Fig. 2 represents an invertedplan view of such machine. Figs. 3 and 4 represent detail sectionalviews upon an enlarged scale, illustrating certain parts of the machine.Fig. 5 represents a face view of a portion of the connecting-rod foroperating the feed-shaft; and Fig. 6 represents a section thereof on thedotted line 00 m, Fig. 5.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the bed of the machine, and B the fixed arm or goose-neckmounted thereon. O is the main shaft, arranged to work within said armor goose-neck, and serving to communicate motion to the needle-bar, theshuttle-carrying lever, and the feeding device of the machine. Securedto the shaft U, within the rear upright portion of the arm B, is aneccentric, D, 011 which is fitted a yoke, E,-for

actuating both the feeding device and the shuttle-carryin g lever.

The shuttle-carrying lever F, which is pivoted at a to the under side ofthe bed A, is

operated by meansof a shuttle-operatin g lever,

a lateral movement to the said feed-bar to feed the cloth forward. Thesaid feed-bar J is supported at f, and the turning of the cam I movessaid bar forward against the pressure of a spring, 9.

In order to give the feed-bar J the required vertical movement I employa slider-bar, K, pivoted at h to an arm, F, extending from theshuttle-carrying lever F, and reciprocated by the oscillation ofthc saidshuttle-carrying lever. The said bar K is held up by a support, L, andupon its upper face is an incline, i, acting as a wedge to raise the barJ, as clearly represented in Fig. 3. Upon the end of the shaft H isarranged a crank, M, and N designates a connecting-rod connected to saidcrank and pivoted at j to the yoke E of the eccentric D.

The turning of the needle-shaft 0 through the medium of theconnecting-rodN oscillates the feed-shaft H and causes the cam I tooperate the feed-bar J.

As before stated, the cam I is tapered in the direction of the length ofthe shaft H, and by moving said shaft longitudinally a portion of thecam, having greater or less prominence, is brought in position to actupon the born or arm 6 of the feed-bar J, and the length of the stitchvaried as required.

In order to provide for properly adjusting the shaft H longitudinallyand holding it in position when adjusted, I employ a clutch-arm, 0,extending from a slide, 0, and having its end forked and fitting in anannular groove, k,

in the hub of the crank M. The slide fits in a hole or socket, Z, in theframe of the machine, and is provided with an internallyscrew-threadedsocket, m. as clearly shown in Fig. 4.

P designates an adjusting spindle or screw having a cylindric portion,a, fitting the hole I, and a screw=threaded end, 0, for engaging withsaid screw-socket m and moving the slide 0, and with it, through themedium of the arm 0, the feed-shaft H, in a longitudinal direction. Byturning the head 19 of the adj ustin'g-screw P in either direction theposition of the shaft H will be varied.

The longitudinal movement of the shaft H will necessarily throw theconnecting-rod N out of line, and to provide for this, and prevent thebearings in the ends of the connecting-rod from heating, I constructsaid rod with pivoted boxes 1%, the construction of which is clearlyshown in Figs. and 6. Each end of the rod is forked, and the boxes R,which are composed of solid blocks, are cut through upon one side of thebearing at s, and are fiat upon opposite sides, and fitted in the forkedends of the connecting-rod, the inner sides of the forks formingbearing-surfaces for the boxes. These boxes are secured Within the forksby pins or screws 73, passing through both the boxes and forks.

When the connecting-rod is out of line the box may turn within the fork,as shown in Fig. 6, so as to remain in line with the journals andprevent the binding of the boxes.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of the feed-bar J, provided with a horn or arm, a,the feed-shaft H, mechanism for oscillating said feed-shaft, theclutch-arm O, slide 0, and screw P, for adjusting said shaftlongitudinally, the tapercam rigidly fixed to the shaft H, theshuttlecarrying lever F and mechanism for oscillating it, and theslider-bar K, attached to and reciprocated by said lever, all organizedand operating substantially as and for the purpose herein set forth.

2. The combination, with an oscillating and longitudinally-adjustablefeed-shaft, a crank upon said shaft, a rotating shaft and eccentric foroperating said feed-shaft, and a yoke fitted to said eccentric, ofa'connecting-rod connecting said yoke and crank, forked at each end,boxes for said connecting-rod which are flat upon opposite sides and arefitted into the forked ends of said rod, the inner surfaces of the forksforming bearing-surfaces for said boxes, and pins or screws for pivotingsaid boxes in a direction transverse to the said shafts, substantiallyas specified.
